In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: Hold module reference while requesting a module User space may unload ip_set.ko while it is itself requesting a set type backend module, leading to a kernel crash. The race condition may be provoked by inserting an mdelay() right after the nfnl_unlock() call. • https://git.kernel.org/stable/c/a7b4f989a629493bb4ec4a354def784d440b32c4 https://git.kernel.org/stable/c/e5e2d3024753fdaca818b822e3827614bacbdccf https://git.kernel.org/stable/c/6099b5d3e37145484fac4b8b4070c3f1abfb3519 https://git.kernel.org/stable/c/0e67805e805c1f3edd6f43adbe08ea14b552694b https://git.kernel.org/stable/c/5bae60a933ba5d16eed55c6b279be51bcbbc79b0 https://git.kernel.org/stable/c/90bf312a6b6b3d6012137f6776a4052ee85e0340 https://git.kernel.org/stable/c/ba5e070f36682d07ca7ad2a953e6c9d96be19dca https://git.kernel.org/stable/c/456f010bfaefde84d3390c755eedb1b0a •

CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-56631 – scsi: sg: Fix slab-use-after-free read in sg_release()
https://notcve.org/view.php?id=CVE-2024-56631
In the Linux kernel, the following vulnerability has been resolved: scsi: sg: Fix slab-use-after-free read in sg_release() Fix a use-after-free bug in sg_release(), detected by syzbot with KASAN: BUG: KASAN: slab-use-after-free in lock_release+0x151/0xa30 kernel/locking/lockdep.c:5838 __mutex_unlock_slowpath+0xe2/0x750 kernel/locking/mutex.c:912 sg_release+0x1f4/0x2e0 drivers/scsi/sg.c:407 In sg_release(), the function kref_put(&sfp->f_ref, sg_remove_sfp) is called before releasing the open_rel_lock mutex. The kref_put() call may decrement the reference count of sfp to zero, triggering its cleanup through sg_remove_sfp(). This cleanup includes scheduling deferred work via sg_remove_sfp_usercontext(), which ultimately frees sfp. After kref_put(), sg_release() continues to unlock open_rel_lock and may reference sfp or sdp. If sfp has already been freed, this results in a slab-use-after-free error. Move the kref_put(&sfp->f_ref, sg_remove_sfp) call after unlocking the open_rel_lock mutex. This ensures: - No references to sfp or sdp occur after the reference count is decremented. - Cleanup functions such as sg_remove_sfp() and sg_remove_sfp_usercontext() can safely execute without impacting the mutex handling in sg_release(). The fix has been tested and validated by syzbot. • https://git.kernel.org/stable/c/cc833acbee9db5ca8c6162b015b4c93863c6f821 https://git.kernel.org/stable/c/3a27c0defb0315760100f8b1adc7c4acbe04c884 https://git.kernel.org/stable/c/59b30afa578637169e2819536bb66459fdddc39d https://git.kernel.org/stable/c/1f5e2f1ca5875728fcf62bc1a054707444ab4960 https://git.kernel.org/stable/c/f10593ad9bc36921f623361c9e3dd96bd52d85ee •
